After months of investigation regarding the German government’s support of Daimler’s continued use of R134a — in violation of a law mandating use of refrigerants “with a global warming potential no more than 150 times that of carbon dioxide” — the European Commission has given Germany two months to comply with the law, or be fined and taken to court.

The legal struggle has heated up between Daimler and the European Commission over the automaker’s continued use of R134a air conditioning refrigerant, which has been banned by the EU, in some of its models. “We are opening a procedure against Germany. This is not a final decision by the Commission,” EU industry commissioner Antonio Tajani said.

Germany has two months to respond. The procedure for adjudicating the violation of EU rules is a multi-step process which normally takes months. The German government is backing Mercedes-Benz and the dispute could ultimately end up in the European Court of Justice, with the possibility of heavy fines and the recall of about 130,000 Mercedes-Benz A-Class, B class, CLA and SL cars.

Remember R1234yf – the replacement refrigerant for R134a that can be potentially fatal, rather than just harmful to the environment? After a protracted battle between Mercedes-Benz and the EU over the use of the new refrigerant, which is flammable and extremely toxic, the adoption of R1234yf appears to be in full swing.

In the continuing saga of Daimler, the EU and banned refrigerants, the German automaker won a provisional ruling from France’s highest administrative judicial body to overturn the suspension of the sale of Mercedes-Benz models equipped with R134a refrigerant in those cars’ air conditioning systems. European Union regulators have banned R134a but Daimler claims that the replacement, R1234yf, can create fire and toxicity safety issues. The French Council of State said that authorities in that country must resume registrations of those Mercedes-Benz models while the case goes on.

According to Bloomberg, the court in Paris ruled that there is “serious doubt” about the immediate environmental threat upon which the French government was basing the sales ban. (Read More…)

The regulatory and verbal war between France and Germany over Mercedes-Benz’s refusal to switch to the R1234yf air conditioning refrigerant has escalated. After a French court ordered a 10 day stay, lifting that country’s ban on R134a equpped A Class, B Class, CLA and SL cars made since June, Daimler expressed confidence that the French government would abide by that ruling. That confidence was apparently badly placed because the French government has now invoked a “safeguard procedure” of the EU that allows member countries to act unilaterally to avoid a serious risk involving the environment, public health or traffic safety, reinstituing the ban. Daimler promised that it would continue fighting to allow the sale of those cars in France. It claims that the new refrigerant is dangerously flammable and toxic. (Read More…)

After a French court lifted that country’s ban on Mercedes-Benz cars equipped with R134a air conditioning refrigerant, saying that the French ministry for the environment must reevaluate their decision to block those cars, Daimler said that it was “very confident’ that the French government will abide by that court ruling. R134a has been banned for use in new model cars by the EU since the start of 2013.

Last week, the European Union Commission’s Technical Committee on Motor Vehicles meeting affirmed France’s refusal to allow Mercedes-Benz to sell cars using R134a refrigerant, and alsom indicated that other EU countries may block the sale of those cars as well. Now, Honeywell International, which owns the rights to R1234yf, (the only refrigerant currently approved by the EU) said that Daimler’s concerns are unfounded. M-B had run tests showing that under certain circumstances, leaks in the air conditioning system could cause underhood fires, and that when it burns, R1234yf produces poisonous hydrogen flouride gas.

When we last reported on France banning some Mercedes-Benz vehicles because the company refuses to use the now mandated R1234yf refrigerant, representatives from all 28 EU member states were scheduled to meet with the EU’s Technical Committee on Motor Vehicles to discuss the matter, particularly as it regards the sale of M-B vehicles in the 27 other EU countries besides France. That meeting has since taken place and according to a memo issued by the European Commission, those representatives have confirmed that all new vehicles sold throughout the EU must use R1234yf, and that any vehicles with the now banned R134a must be withdrawn from the market in all EU states. The dispute is over the fire safety of the new refrigerant. R134a was banned because it is considered a greenhouse gas. (Read More…)
